To provide an image projection device with which it is possible to maintain high freedom of design even when different regions of a display unit are irradiated with a plurality of images, and reduce the number of emission planes of a light-emitting element that are needed for suppressing luminance unevenness.SOLUTION: The image projection device comprises an image display unit that displays a projection image, a light irradiation unit that irradiates the image display unit with irradiation light, and an irradiation optical unit that irradiates irradiation light as a projection image in the viewpoint direction via the display unit. The projection image includes a first and a second image that are projected to different regions of the display unit. The image display unit is provided with a first region (17b) that displays the first image, and a second region (17a) that displays the second image. The light irradiation unit has first light source units (12b, 13b) that irradiate the first region (17b) with light, and second light source units (12a, 13a) that irradiate the second region (17a) with light, the first light source units (12b, 13b) and the second light source units (12a, 13a) being arranged such that their longitudinal directions are inclined by an angle θ with respect to each other.SELECTED DRAWING: Figure 3

    【課題】表示部の異なる領域に複数の画像を照射しても設計自由度を高く維持し、輝度ムラを抑制するために必要な発光素子の発光面数を低減することが可能な画像投影装置を提供する。【解決手段】投影画像を表示する画像表示部と、画像表示部に対して照射光を照射する光照射部と、表示部を介して照射光を投影画像として視点方向に照射する照射光学部とを備え、投影画像は表示部の異なる領域に投影される第1画像および第2画像を含み、画像表示部は、第1画像を表示する第1領域(17b)と、第2画像を表示する第2領域(17a)を備え、光照射部は、第1領域(17b)に対して光を照射する第1光源部(12b,13b)と、第2領域(17a)に対して光を照射する第2光源部(12a,13a)を有し、第1光源部(12b,13b)の長手方向と第2光源部(12a,13a)の長手方向は互いに角度θだけ傾いて配置されている。【選択図】図3
